Creamy pesto chicken pasta combines tender chicken breast with basil pesto cream sauce and al dente pasta. This high protein, mediterranean-inspired family dinner is fresh, flavorful, and ready in 25 minutes.
Bring a large pot of salted water to a boil, add penne pasta, and cook until just al dente according to package instructions (about 9–10 minutes). Reserve 1/2 cup pasta water before draining.
While pasta cooks, heat 2 tbsp olive oil in a large skillet over medium-high heat. Cut chicken breast into 1-inch pieces, season with 1/4 tsp each salt and black pepper, and sauté until golden and cooked through, about 4–5 minutes. Remove chicken and set aside.
Lower the heat to medium, add minced garlic to the pan, and sauté for 30 seconds until fragrant, being careful not to brown the garlic.
Pour in heavy cream and stir, scraping up browned bits. Return chicken to the pan. Simmer 2 minutes, then add basil pesto and half of the parmesan cheese, stirring until a creamy sauce forms and is just heated through.
Add drained pasta and 1/4 cup reserved pasta water to the sauce, tossing over low heat until pasta is evenly coated. Add extra pasta water if desired for a creamier texture. Finish with the remaining parmesan. Serve immediately.
